Oncologic cervicofacial surgery and plastic surgery have had a common evolution over the last 50 years where progress erasing from one was beneficial to the other one. We review here the historical evolution of these specialties and present the state of the art of plastic surgery in the field of cervicofacial oncology.
BACKGROUND: The optimal primary treatment for posterior pharyngeal wall tumors remains controversial. METHODS: To assess the relevance of surgical treatment from a functional and oncologic point of view, we reviewed the cases of 77 patients surgically treated between 1984 and 1995. Among them 23 had been previously irradiated. Fifty-five patients underwent a conservative surgery (CS) sparing the larynx; 19 direct closures, 6 reconstructions of the posterior wall with a thoracic myocutaneous flap, 15 with a platysma flap, and 15 with a free forearm flap were performed. Twenty-two patients underwent radical surgery (RS). All previously untreated patients had postoperative radiotherapy. The functional assessment concerned the CS group. Oncologic results, especially local control and survival were studied for the whole group. RESULTS: Of the 55 patients who underwent CS, 53 (96%) had their canula and 49 (89%) their feeding tube removed. At 1 year, in the platysma and free forearm groups, 21 of the 24 assessable patients were back to exclusive oral intake. For patients treated by primary surgery followed by radiotherapy, the rate of local failure was 11% (18% for tumors greater than 4 cm), and the 5-year survival rate was 35%. For patients who had previous radiotherapy, the rates were, respectively, 52% and 16%. CONCLUSION: The satisfactory functional results, caused by the improvement of reconstructive procedures, allow conservative surgery even in the case of large tumors. Oncologic results, especially local control, suggest that primary surgery followed by radiotherapy is effective for the treatment of posterior wall cancer. The oncologic results of surgery in a previously irradiated area are poor, and CS is not recommended in these cases.
PATIENTS AND METHODS: Between 1974 and 1997, 297 patients underwent a subtotal laryngectomy at the Institut Gustave-Roussy; 146 of these patients underwent cricohyoidopexy (CHP) for a supraglottic primary as their first treatment. The majority of patients were men (137) aged from 33 to 78 years (median 54 years). The tumour stage at presentation was T1 in 2, T2 in 87, T3 in 53 (preepiglottic space involvement), and T4 (minimal thyroid cartilage invasion) in 4 patients. One hundred and twenty-five patients were N0 (86%) and 21 patients were Np (palpable); 98% had homolateral and 55% had bilateral neck dissections. RESULTS: One patient died postoperatively of a myocardial infarction and 68% patients had an uneventful course. Aspiration was the commonest complication (23 patients, 19%). The median time to removal of the tracheotomy cannula was 10 days and for the nasogastric tube 21 days during the past 10 years. Completion of subtotal laryngectomy into total laryngectomy was done in 21 cases (15%): eight times because of oncological events [five local failures, two second primary (hypopharynx), one positive margin] and 13 times because of aspiration (9%). There were six local failures (4%) and eight nodal failures (5%). The rates of distant metastases and second primaries were 6% and 16% respectively. Half of the local and nodal failures were subsequently sterilized. Findings at death were two local recurrences, four nodal recurrences, eight distant metastases, and 11 second primaries. The 3- and 5-year overall survival rates were 92% and 88% respectively, with an overall laryngeal preservation rate of 86%. CONCLUSION: When supraglottic laryngectomy is not feasible for supraglottic cancer, subtotal laryngectomy with CHP is a safe and effective oncological procedure, with preservation of satisfactory laryngeal function.
Reconstruction of the oropharynx and the hypopharynx is difficult due to their wide diameters. We report eight cases of circumferential pharyngolaryngectomies for epidermoid carcinomas of the hypopharynx extended to the oropharynx and classified T4. Reconstruction was performed with a U-shaped free jejunal transplantation. This specific technique consists of a side to side anastomosis between two loops of jejunum. It facilitates reconstruction at the level of the oropharynx and diminishes postoperative complications.
STUDY AIM: Midface is situated between the occlusal plane and the transverse midorbital plane. The aim of midface reconstruction is to restore the bony and soft tissue contour of the face, to obtain a rigid support for the velum, to allow oronasal separation, and to allow support for the orbit and obliteration of the maxillary sinus in order to restore the main functions: respiration, speech, deglutition, mastication, olfaction, vision. PATIENTS AND METHODS: Between 1988 and 1997, 65 patients with defects to the midface in relation with cancer (n = 60), gunshot (n = 3), or congenital malformation (n = 2), underwent reconstruction with one or more transplants: forearm (n = 21), latissimus dorsi (n = 23), scapula (n = 12), composed subscapula (n = 10), and fibula (n = 4). Forty-seven of the patients were men and 18 were women. The mean age was 56 years (12-90 years). In patients with cancer, tumoral resection was immediately followed by midface reconstruction in the last 43 cases. Free flaps were selected for reconstruction of each part of the midface: cheek, nose, orbit floor, maxillary and palate. RESULTS: One post-operative death occurred (1.5%). The morbidity rate (18.7%) included necrosis of the free flaps in four cases. Average resumption of oral intake was ten days. The mean time to discharge was 17 days. Aesthetic and functional results were rated good or excellent in 53 patients. After one year, 52 patients were alive. Oral intake was normal in 48 patients, and mixed in four. Speech was excellent or good in 49 patients. From amongst the patients, 80% were able to find a job. CONCLUSION: Free flaps with micro surgery provides an optimal, functional, morphological and aesthetic outcome. Patients with advanced cancer of the midface are best managed through a multidisciplinary team approach. Microsurgical reconstruction represents the technical state of the art in case of extensive and complex midface defect.
This report presents the result of our experience with 13 primary synovial sarcoma of the head and neck. The 9 males and 4 females had a median age of 32 years. The predominant location of the tumor was the pharynx, treatment consist of surgical excision alone or associated with post-operative radiotherapy or chemotherapy. Mean follow-up was 48 month. Local recurrence occurred in 2 patient, 4 patient died of pulmonary metastasis. The five year survival rate was 55%. Favorable prognostic findings included age < 20 years and complete initial resection.
BACKGROUND: Forty-nine cases of circumferential pharyngolaryngectomy with total esophagectomy (PLTE) done between 1982 and 1996 were studied retrospectively. These procedures were performed for advanced squamous cell tumors of the superior esophageal sphincter (n = 23), for hypopharyngeal tumors with synchronous esophageal carcinoma (n = 15), and for hypopharyngeal tumors extensively invading the cervical esophagus (n = 11). METHODS: Ninety-six percent of the patients had T3-4 lesions, and it was impossible to use a free jejunal graft reconstruction. Patients underwent primary surgery in 70% of the cases, and salvage surgery (after failure of chemoradiotherapy) in 30%. In most patients, esophagectomy was performed without thoracotomy (n = 45). Resection was curative (R0) in 70% of the cases, in spite of lymph node invasion in 94%. Reconstruction of the digestive tract was achieved with the stomach in 33 patients (67%) or with the colon in 16 patients (33%). RESULTS: Before 1989, postoperative mortality was high, was correlated with the high frequency of palliative surgery, and resulted in unsatisfactory survival results (overall 5-year survival rate of 7%). After 1989, as a result of better selection of patients and appropriate training of our team, postoperative mortality decreased from 33% to 10%, R1-2 resections decreased from 39% to 26%, and a 3-year overall survival rate of 28% was obtained for the last 25 patients, all of whom were able to eat without difficulty. These results are superior to the survival rates and functional results obtained with radiochemotherapy alone for such advanced tumors, even though the voice is preserved with radiochemotherapy alone. CONCLUSIONS: PLTE for advanced pharyngeal or cervical esophageal tumors is the best treatment currently available, but it is indicated only in very selected cases: when it is technically impossible to perform reconstruction with a free jejunal graft after circumferential pharyngolaryngectomy; as primary surgery, rather than as salvage surgery following chemoradiotherapy; after careful preoperative morphologic and endoscopic assessment of the extent of the tumor; and in patients able to tolerate a thoracotomy for an esophagectomy with lymphadenectomy. Selection according to these guidelines should improve results.
In order to understand the risks and benefits of a combined transfacial and neurosurgical procedure for neoplasms of the ethmoid sinus, we reviewed all patients who underwent this surgical approach in our department between 1986 and 1994. The study included 41 patients. Pathological diagnoses included adenocarcinoma (31 patients), squamous cell carcinoma (three patients), aesthesioneuroblastoma (three patients), other (four patients). The overall morbidity rate was 39 per cent, and the post-operative mortality rate was 2.5 per cent. Complications were statistically more likely in patients with bone skull base reconstruction. The main carcinologic failures were local recurrences (24 per cent) and metastases (22 per cent). The one-year, three-year and five-year Kaplan Meir survival rates were respectively 84 per cent, 53 per cent and 36 per cent. In conclusion, the mortality and morbidity were acceptable, especially when no bone skull base reconstruction was performed. Better local control justifies a combined procedure with post-operative radiotherapy when tumours involve or reach the skull base.
Forty patients were treated or followed up for aesthesioneuroblastoma between 1980 and 1995 at Institut Gustave Roussy, France. There were three T1, seven T2, 15 T3 and 15 T4 lesions. The cervical metastatic rate at presentation was 18 per cent. Distant metastases were detected by bone marrow biopsy and bone scan in three patients at presentation. Treatment modalities included surgery alone in eight patients, radiotherapy alone in three patients, combined modality surgery plus radiotherapy in 11 patients, chemotherapy alone in two patients, chemotherapy plus radiotherapy in 10 patients, and multimodality therapy chemotherapy plus surgery plus radiotherapy in six patients. The five-year survival rate was 51 per cent. Multimodality treatment offered better survival (63 per cent at five years) and disease-free interval (54 months). Overall local, regional, and distant failure rates were 58 per cent, 15 per cent and 40 per cent respectively. Distant metastases commonly occurred in bone (82 per cent). Cervical metastasis was an unfavourable prognostic indicator (0 per cent survival at two years). In conclusion, aesthesioneuroblastoma is sensitive to chemotherapy and radiotherapy. Multimodality therapy should be used initially.
The free jejunal autograft (FJA) has become a common procedure for pharyngeal reconstruction after circumferential pharyngolaryngectomy. In order to evaluate the postoperative outcome and the functional and carcinologic results, we retrospectively reviewed 83 cases of reconstruction with FJA. Fifty-one patients had received no prior radiotherapy, and 25 had received prior radiotherapy for their hypopharyngeal tumor or for another previous primary. Seven patients underwent a secondary reconstruction. In the postoperative course, there were 2 postoperative deaths, 4 graft failures (5%), and 11 salivary fistulas. The median time to removal of the nasogastric tube was 16 days, and to discharge, 23 days. Forty-eight patients received postoperative radiotherapy, with good tolerance. At 1 year postoperatively, 98% of the patients were able to eat a solid or soft diet. The postoperative radiotherapy did not impair the quality of the functional results in a long-term assessment. The vocal results were disappointing. The 3-year survival rate was 40%. The main carcinologic failures (45 patients) were locoregional recurrences (20 patients) and metastasis, which was the cause of death in 34% of the cases. It seems clear that FJA allows one-stage reconstruction and good swallowing rehabilitation, tolerates postoperative radiotherapy, and increases the quality of life in these patients with a poor prognosis.
PURPOSE: To review our experience using full-dose external reirradiation given with a curative intent for patients with unresectable head and neck carcinoma (HNC). PATIENTS AND METHODS: Between January 1980 and December 1996, 169 patients who presented with unresectable nonmetastatic HNC in a previously irradiated area were included in this series. The median time between the first and the second irradiation was 33 months. Reirradiation protocols were as follows: radiotherapy alone (65 Gy over 6.5 weeks at 2 Gy/d), 27 patients; Vokes protocol, ie, five to six cycles of radiotherapy (median total dose, 60 Gy; 2 Gy/d) with simultaneous fluorouracil (5-FU) and hydroxyurea, 106 patients; and bifractionated radiotherapy (median total dose, 60 Gy; 2 x 1.5 Gy/d) with concomitant mitomycin, 5-FU, and cisplatin, 36 patients. The median cumulative dose of the two irradiations was 120 Gy. Eighty-five percent of the tumors were squamous cell carcinoma, 14% undifferentiated carcinoma of nasopharyngeal type, and 1% adenocarcinoma. Forty-four percent were local recurrences, 23% nodal recurrences, 14% both local and nodal, and 19% second primary tumors. RESULTS: Mucositis grade 3 (World Health Organization [WHO]) was found in 32% and grade 4 in 14% of cases. Four patients presented with neutropenia or thrombocytopenia (grade 3 or 4 WHO). Late toxicities (> 6 months) were as follows: cervical fibrosis (grade 2 to 3 Radiation Therapy Oncology Group [RTOG]), 41%; mucosal necrosis, 21%; osteoradionecrosis, 8%; and trismus, 30%. Five patients died of carotid hemorrhage, apparently in complete remission. Six months after the onset of reirradiation, 37% of patients were in complete response. Patterns of failure were local only (53%), nodal only (20%), metastatic only (7%), and multiple (20%). Median follow-up time was 70 months. Overall survival rate (Kaplan-Meier) was 21% (95% confidence interval [CI], 15% to 29%) at 2 years and 9% (95% CI, 5% to 16%) at 5 years. Median survival time was 10 months for the entire population. Thirteen patients, of whom 12 were treated with the Vokes protocol, were long-term disease-free survivors. In a multivariate analysis, the volume of the second irradiation was the only factor significantly associated with the risk of death: relative risk=1.8 (95% CI, 1.13 to 5.7) (P=.01). CONCLUSION: Full-dose reirradiation combined with chemotherapy was feasible in patients with inoperable HNC. The incidence and severity of late toxicity was markedly increased in comparison to that observed after the first irradiation. Median survival was better than that generally obtained using palliative chemotherapy alone. A small proportion of patients were long-term disease-free survivors.
Isolated mandibular metastasis from a thyroid cancer is exceptional. In our observation, it was revealed 13 years after the thyroid cancer (papillo-vesicular carcinoma which was treated with total thyroidectomy, nodes resection and I 131). Treatment included interruptive mandibulectomy and reconstruction with a free composed vascularized fibular transplant. Follow-up was uneventful. Functional and morphological results were excellent. Isolated cases are reported in the literature. Surgical resection must be achieved. The originality of our observation is the mandibular reconstruction with a free vascularized fibular transplant.
UNLABELLED: The treatment of synchronous esophageal and head and neck carcinomas is difficult. MATERIAL AND METHOD: Retrospective study of 33 patients treated with esophagectomy for an intrathoracic squamous cells carcinoma discovered during pan-endoscopy for a synchronous head and neck cancer. RESULTS: In 7 cases (21%) it was advanced (pT3-4) esophageal cancers. The hospital mortality was 9%. Five year survival was 18% without stabilization of the survival curve, 60% of patients died of recurrence of tumor. CONCLUSION: Esophagectomy is suitable for usT1-2 tumors if surgery is also indicated for the head and neck tumor. Radiochemotherapy is indicated for advanced usT3-4 esophageal tumors or when the treatment of the head and neck tumor is not surgery.
Reconstruction of the oro and hypopharynx has specific difficulties due to their wide diameters. Seven patients underwent reconstruction with a free U-shaped jejunal transplant, after circular pharyngolaryngectomy for hypopharyngeal cancer invading the oropharynx. This transplant included a side-to-side anastomosis between the two limbs of the jejunal loop. This transplant allowed reconstruction of the upper digestive tract after wide carcinologic resection of the pharynx. The U-shaped jejunal transplant facilitated the upper anastomosis, especially at the upper part where the resection involved the oropharynx. It formed a reservoir behind the tongue, and avoided nasal reflux. The best indications are large resections involving the oropharynx.
Cancers of nasal cavities and paranasal sinuses represent about 2-3% of cancers of the upper aerodigestive tract, in France. In 20% of these cases, these cancers develop in the ethmoid region, 80% of them being adenocarcinomas. Among the distinctive features of adenocarcinomas, epidemiological data should be emphasized. Indeed, ethmoid adenocarcinomas are mostly linked to wood exposure, mainly hard and exotic woods. However, in synthetic wood, binding agents and glues may also be involved as cocarcinogens. These cancers are often underdeclared by medical professionals leading to possible prejudice to the patient and his entitled beneficiaries. Therefore a detailed professional history of all patients presenting with a cancer of the nasal cavities and/or paranasal sinuses should be undertaken to avoid such a situation.
In 1991, a retrospective study was conducted by the French Cancer Centers Group. It concerned 752 cancers of the nasal cavities and paranasal sinuses, among which 61 were adenoid cystic carcinomas and 64 esthesioneuroblastomas. Local aggressiveness and high metastatic potential of adenoid cystic carcinomas were confirmed: 27 local relapses, 26 metastases, overall 5-year survival rate at 55%. Concerning esthesioneuroblastomas, the 5-year survival rate was 56% for patients treated with surgery and radiotherapy (7/27 went through combined surgical approaches), and 26% for those treated with radiotherapy alone. Two main factors of poor prognosis can be emphasized: a) intracranial extension: 5-year survival rate at 18% vs 59%, b) immediate node metastases: 5-year survival rate at 11% vs 63%.
Among the mandibular tumours, the secondary malignant tumours are uncommon. We relate 7 cases observed between 1977 and 1995. Two cases have revealed the original cancer (rectum, prostate). The five other cases were discovered during the evolution of the original cancer (colon, lung, kidney, thyroid, breast). These 7 mandibular metastases were isolated. The treatment included a mandibular resection in 6 cases. In one of these cases, the reconstruction was performed with a free vascularized fibular transplant with success. Among the seven cases, two patients are alive, at the present time, with a mean follow-up of 3 years. This justifies a curative treatment.
In six suffocating patients with a severe upper airway obstruction (three patients after direct laryngoscopy under general anaesthesia and three patients with cervical tumor scheduled for a difficult tracheostomy), jet-ventilation was delivered using a transtracheal catheter. The jet-ventilator insufflated oxygen only when the tracheal pressure was below a preset value, during spontaneous inspiration. During expiration, tracheal pressure increased above the preset value, the ventilator stopped the insufflation and the expiratory gases escaped through the upper airway. This method corresponds to an inspiratory support without intubation. In post-anaesthesia patients, oxygenation and alveolar ventilation were improved, allowing the avoidance of tracheostomy. In the other patients, tracheostomy was made possible with good surgical conditions under general anaesthesia. This method can be applied in conscious patients and allows oxygenation of suffocating patients.
